Plastic Miter Gears
 |
Gears Sold Separately |
 | |
Connect two shafts at a right angle without changing shaft speed or torque. Made of plastic, these gears run quieter than metal gears and have good corrosion and chemical resistance.
For two gears to mesh correctly, they must have the same pressure angle, pitch/module, and number of teeth.
Nylon—Nylon gears are self-lubricating, so they’re often used in food machinery. However, they’re not approved for direct contact with food or chemicals that will come into contact with food.
Acetal—Acetal gears absorb less moisture than nylon gears and are less prone to dimensional change. They’re best suited for use in light duty applications such as prototyping.

High-Power Metal Miter Gears
 |
Keyed Bore with Set Screw |
 |
|
Also known as spiral miter gears, these gears have curved teeth that stay in contact longer than straight teeth so they handle heavier loads at higher speeds. They run quieter than standard miter gears because the teeth gradually engage. Use them to transmit motion at a right angle while maintaining shaft speed and torque. Gears are carbon steel for strength. Teeth are hardened for wear resistance.
Gears must be identical in order to mesh correctly; they're sold as a pair.
